Usris was a Pan-preneur and member of the Crew of the Zaz, and was the pilot and head-technician of the Zaz. Prior to being hired by Leozav Varino he was a pirate captain of the Conclave of Trisysians. He was a founding member who was presumed dead after the Mandalorians destroyed his ship. However, he instead survived having crashed upon the world of Leafar, where a local technician and cyberneticist would save him. He would be hired by Leozav Varino to modify the Zaz which would impress Leozav, who would then hire him on full time as the technician of the Zaz.
